You mean the other way around, right? reiser defaults to tail-packing,
which can cause problems with GRUB and LILO, which is why notail is an
option which turns off tail-packing for those crazy enough to use
reiser on /boot.
If you use notail on the portage tree, you get rid of that advantage,
then Neil is absolutely correct: there's not too much point in
journaling the portage tree, and if you actively make reiser
not-competitive on the storage-space direction, the only metric left
to compare is speed, and ext2 is faster.
Incidentally, if you are willing to sacrifice speed for space, then a
sparsefile for /usr/portage may also be an option.
